The Large Wave form helix easily demonstrates wave phenomena.

Long, pure sounding aluminum tuning forks.

This ripple tank is transparent, acrylic plastic and supported in a sturdy plastic frame.

These long-lasting aluminum tuning forks have a full sound.

Produces circular waves from either one or two point sources. The phase relationship is continuously adjustable. A variable, low voltage power supply, such as our 64250-10, allows the speed to be adjusted also. Securely mounted in a molded housing with four non-skid, shock-absorbing feet.

Designed for Physics and Physical Science experimentation.

This self-contained apparatus explores wave velocity.

High power and versatility.

Equilateral prisms, made from high quality clear acrylic sheet.

Both versions of these economy tuning fork sets come with a mallet designed for one hard and one soft end for use with all frequencies of forks.
